TV from the 50s

[Retro-guy]

Got this TV a while back, its a GRUNDIG ZAUBERSPIEGEL 439 from Germany What worries me a bit is that some chassis rust which means moisture and humidity is not good for these TVs primarily for HV transformer (flyback). Capacitors are definitely bad so need replacment.TV looks pretty easy since all of the fifties TVs were, tubes and two resistors and a capacitor.

Now I recently had a bad experience where I powered a set up not knowing it was exposed to humidity a lot and of course the LOPT(HV-winding) melted shortly after that.Now this TV has some surface rust which means damp environment,Now how can I get the moisture out of the LOPT if it has any in it and how to tell if its been damaged by too much humidity ??


The CRT looks good, the gun inside the tube doesn't look discolored but all silver, which is a good sign maybe is a rebuild/replacement , also tested the filament and it is intact, looks very original ...

how to make sure flyback will not destroy itself if it has moisture in it and get that moisture out
